We use high purity PP material, by the optimized uniaxial stretching process and imported high-precision production line, our separator can offer better safety performance with its uniformed pore size, muti-layer structure auto-shutdown function. It will perfectly satisfy the application for EV power battery and EESS.

High safety

  Multilayer membrane efficiently reduce the safety hazard found by single layer membrane defects: Hardly any TD shrinkage, low MD shrinkage; Perfect heat resistance and antioxidant especially suitable for high/ow voltage system.

Good uniformity

    Using worldwide popular DRY process, insure the pore sizes uniformity and well distributed on membrane. The separator with multilayer lamination structure has better thickness uniformity and will improve Li-ion battery cycle life.

Excellent air permeability

    High porosity, high air-permeability, low sinuosity, is suitable for high rate discharging of the Electric Vehicle Li-ion battery.
